Hernia in Children: Symptoms, Types, Treatment & When Surgery Is Needed

A small lump in your child’s groin or around the belly button can be alarming for any parent. One of the possible causes is a hernia in children, a condition that occurs when tissue pushes through a weak or incompletely closed area of the abdominal wall.

Pediatric hernias are relatively common and are often related to how the abdominal wall develops before birth. Although most can be treated effectively, some require timely surgical intervention to prevent complications.

Understanding the different types of hernias, their symptoms, and available treatment options can help parents recognise when their child needs medical attention.

What Is a Hernia in Children?

A hernia occurs when an internal structure, such as a portion of the intestine or fatty tissue, pushes through a weak area or opening in the surrounding muscle or tissue.

In children, hernias most commonly develop in the groin or around the belly button. Parents may notice a soft lump that becomes more visible when their child cries, coughs, laughs, strains, or engages in physical activity.

The swelling may become less noticeable or disappear when the child relaxes or lies down. However, even if the lump comes and goes, it should be evaluated by a pediatric surgeon.

What Are the Different Types of Hernia in Children?

Inguinal Hernia

An inguinal hernia develops in the groin and is the most common type of hernia requiring surgery in children. It usually occurs when an opening that should close during development before birth remains open, allowing abdominal contents to pass into the groin.

In boys, the swelling may extend into the scrotum. In girls, the hernia may appear as a lump in the groin and can sometimes involve structures such as the ovary.

Inguinal hernias generally do not close on their own and usually require surgical repair because of the risk of the contents becoming trapped.

Umbilical Hernia

An umbilical hernia develops around the belly button when the opening in the abdominal wall does not close completely after birth.

It typically appears as a soft bulge that becomes more prominent when the child cries or strains. Many small umbilical hernias in babies close naturally as the abdominal wall strengthens.

The decision to observe or operate depends on the child’s age, the size of the opening, symptoms, and the findings of a clinical examination.

What Does a Hernia Look Like in a Child?

The appearance of a pediatric hernia can vary depending on its location and size. Common signs include:

• A lump in the groin that comes and goes

• Swelling around the belly button

• A bulge that becomes more noticeable during crying or straining

• Swelling extending into the scrotum in boys with an inguinal hernia

Sometimes, the swelling may not be visible when the child is resting. If you notice a recurring lump, arrange an assessment with a pediatric surgeon rather than assuming it will disappear permanently.

Can a Hernia in a Child Go Away on Its Own?

Whether a hernia closes naturally depends on its type.

Inguinal hernias generally do not close on their own. Surgery is usually recommended to close the abnormal opening and reduce the risk of complications.

Umbilical hernias may close naturally during early childhood. If the hernia is small and does not cause symptoms, the surgeon may recommend monitoring it for a period of time.

Parents should not attempt to push a painful or firm lump back into place. Medical assessment is important to determine the appropriate treatment.

When Is a Hernia in Children an Emergency?

Although many pediatric hernias are treatable, an inguinal hernia can sometimes become incarcerated, meaning its contents become trapped. In more serious cases, the blood supply to the trapped tissue may be compromised.

Seek emergency medical attention if your child develops any of the following symptoms:

• A lump that becomes hard, swollen, or very painful

• Persistent swelling that does not disappear as it normally does

• Red, purple, or discoloured skin over the lump

• Vomiting or significant abdominal pain

• Abdominal swelling or unusual distress

These symptoms may indicate a serious complication requiring urgent treatment. Do not wait for the symptoms to resolve on their own.

How Is a Pediatric Hernia Diagnosed?

In most cases, a pediatric surgeon can diagnose a hernia through a physical examination. The doctor will examine the abdomen, groin, and, in boys, the scrotum to assess the location and characteristics of the swelling.

An ultrasound is not always necessary, but it may be recommended if the diagnosis is uncertain or another condition is suspected.

An accurate diagnosis helps the surgeon distinguish a hernia from other causes of swelling, including a hydrocele.

Does a Child Need Surgery for a Hernia?

Treatment depends on the type of hernia, the child’s age, symptoms, and the risk of complications.

Treatment for Inguinal Hernia

Surgical repair is generally recommended for inguinal hernias because the opening usually does not close spontaneously. The timing of surgery depends on the child’s age, medical condition, and the surgeon’s assessment of the risk of the hernia becoming trapped.

Treatment for Umbilical Hernia

Small, uncomplicated umbilical hernias in young children can often be monitored because they may close naturally. Surgery may be considered if the hernia persists beyond the expected age for spontaneous closure, is unusually large, causes symptoms, or develops complications.

A pediatric surgeon can explain the most appropriate treatment plan for your child.

What Happens During Pediatric Hernia Surgery?

Pediatric hernia repair is performed under anaesthesia. The surgeon returns the herniated tissue to its normal position and closes the abnormal opening.

Depending on the type of hernia, the child’s age, and the surgeon’s assessment, the procedure may be performed using an open surgical technique or a minimally invasive laparoscopic approach.

The surgeon will discuss the benefits, limitations, and suitability of each technique before the procedure.

What Is Recovery Like After Hernia Surgery?

Children generally recover well after uncomplicated hernia surgery. Some temporary discomfort, mild swelling, or soreness around the surgical site may occur.

The surgical team may recommend appropriate pain relief and provide instructions for wound care, bathing, physical activity, and follow-up appointments.

Most children gradually return to their normal routines according to their surgeon’s advice. Parents should contact the medical team if their child develops worsening pain, fever, increasing redness, persistent vomiting, or other concerning symptoms.

Hernia vs. Hydrocele: What Is the Difference?

A hernia and a hydrocele can sometimes look similar, particularly in boys, because both may cause swelling in the groin or scrotum.

An inguinal hernia occurs when abdominal contents pass through an opening into the groin or scrotum. A hydrocele is a collection of fluid around the testicle.

Although both conditions can cause visible swelling, their treatment and urgency may differ. A pediatric surgeon can assess the swelling and determine whether further investigation or treatment is required.

Frequently Asked Questions About Hernia in Children

Is a Hernia in a Child Dangerous?

Most pediatric hernias can be treated effectively. However, an inguinal hernia can become trapped and, in severe cases, compromise the blood supply to the affected tissue. Prompt assessment and appropriate treatment help reduce this risk.

Does Crying Cause Hernias in Babies?

Crying does not usually cause the underlying defect. However, it increases pressure inside the abdomen, making an existing hernia more visible.

Can a Child Play Sports With a Hernia?

Activity recommendations depend on the type of hernia, the child’s symptoms, and the treatment plan. Consult a pediatric surgeon for advice about physical activity before and after surgery.

Is Laparoscopic Hernia Surgery Better for Children?

Both open and laparoscopic techniques can be effective. The most suitable approach depends on the child’s age, anatomy, whether one or both sides are affected, and the surgeon’s experience.

Can a Hernia Return After Surgery?

Recurrence after pediatric hernia repair is uncommon, but it is possible. Following postoperative instructions and attending recommended follow-up appointments help the surgical team monitor recovery.

When Should You Consult a Pediatric Surgeon?

If you notice a recurring lump in your child’s groin, scrotum, or belly button, do not panic, but do not ignore it either. A clinical examination can help determine whether the swelling is a hernia, hydrocele, or another condition and whether treatment is necessary.

Dr. Jui Mandke, a pediatric and neonatal surgeon and pediatric laparoscopic surgeon, has experience in the surgical management of pediatric hernias and other childhood surgical conditions.

Consulting a qualified pediatric surgeon can help you understand your child’s condition, the available treatment options, and the next steps towards appropriate care.
